drm/i915/fbdev: Stop repeating tile configuration on stagnation

2017-03-09T08:43:17+00:00

If we cease making progress in finding matching outputs for a tiled configuration, stop looping over the remaining unconfigured outputs. v2: Use conn_seq (instead of pass) to only apply tile configuration on first pass.

drm: Rely on mode_config data for fb_helper initialization

2017-02-02T18:12:00+00:00

Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

drm/i915: Track pinned vma in intel_plane_state

2017-01-19T10:14:09+00:00

With atomic plane states we are able to track an allocation right from preparation, during use and through to the final free after being swapped out for a new plane. We can couple the VMA we pin for the framebuffer (and its rotation) to this lifetime and avoid all the clumsy lookups in between. v2: Remove residual vma on plane cleanup (Chris) v3: Add a description for the vma destruction in intel_plane_destroy_state (Maarten) References: https://bugs.freedesktop.org/show_bug.cgi?id=98829 Signed-off-by: Chris Wilson Signed-off-by: Maarten Lankhorst Link: http://patchwork.freedesktop.org/patch/msgid/20170116152131.18089-1-chris@chris-wilson.co.uk Acked-by: Joonas Lahtinen

Also pulled back -rc2 in first to resync with drm-intel-fixes and make sure I can reuse the exact rerere solutions from drm-tip for safety, and because I'm lazy. Signed-off-by: Daniel Vetter

Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8. Less duplicated information is a good thing. Note that I didn't put parens around the cpp*8 in the below cocci script, on account of not wanting spurious parens all over the place. Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any. There are some cases where previously the code did X*bpp/8, so the division happened after the multiplication. Those are now just X*cpp so the division effectively happens before the multiplication, but that is perfectly fine since bpp is always a multiple of 8. @@ struct drm_framebuffer *FB; expression E; @@ drm_helper_mode_fill_fb_struct(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ i9xx_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ ironlake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer *FB; expression E; @@ skylake_get_initial_plane_config(...) { ... - FB->bits_per_pixel = E; ... } @@ struct drm_framebuffer FB; expression E; @@ ( - E * FB.bits_per_pixel / 8 + E * FB.format->cpp[0] | - FB.bits_per_pixel / 8 + FB.format->cpp[0] | - E * FB.bits_per_pixel >> 3 + E * FB.format->cpp[0] | - FB.bits_per_pixel >> 3 + FB.format->cpp[0] | - (FB.bits_per_pixel + 7) / 8 + FB.format->cpp[0] | - FB.bits_per_pixel + FB.format->cpp[0] * 8 | - FB.format->cpp[0] * 8 != 8 + FB.format->cpp[0] != 1 ) @@ struct drm_framebuffer *FB; expression E; @@ ( - E * FB->bits_per_pixel / 8 + E * FB->format->cpp[0] | - FB->bits_per_pixel / 8 + FB->format->cpp[0] | - E * FB->bits_per_pixel >> 3 + E * FB->format->cpp[0] | - FB->bits_per_pixel >> 3 + FB->format->cpp[0] | - (FB->bits_per_pixel + 7) / 8 + FB->format->cpp[0] | - FB->bits_per_pixel + FB->format->cpp[0] * 8 | - FB->format->cpp[0] * 8 != 8 + FB->format->cpp[0] != 1 ) @@ struct drm_plane_state *state; expression E; @@ ( - E * state->fb->bits_per_pixel / 8 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel / 8 + state->fb->format->cpp[0] | - E * state->fb->bits_per_pixel >> 3 + E * state->fb->format->cpp[0] | - state->fb->bits_per_pixel >> 3 + state->fb->format->cpp[0] | - (state->fb->bits_per_pixel + 7) / 8 + state->fb->format->cpp[0] | - state->fb->bits_per_pixel + state->fb->format->cpp[0] * 8 | - state->fb->format->cpp[0] * 8 != 8 + state->fb->format->cpp[0] != 1 ) @@ @@ - (8 * 8) + 8 * 8 @@ struct drm_framebuffer FB; @@ - (FB.format->cpp[0]) + FB.format->cpp[0] @@ struct drm_framebuffer *FB; @@ - (FB->format->cpp[0]) + FB->format->cpp[0] @@ @@ struct drm_framebuffer { ... - int bits_per_pixel; ... }; v2: Clean up the 'cpp*8 != 8' and '(8 * 8)' cases (Laurent) v3: Adjusted the semantic patch a bit and regenerated due to code changes Signed-off-by: Ville Syrjälä Reviewed-by: Laurent Pinchart Reviewed-by: Alex Deucher (v1) Link: http://patchwork.freedesktop.org/patch/msgid/1481751140-18352-1-git-send-email-ville.syrjala@linux.intel.com
